Comment (by cehoyos):

 I tested the following command line with current ffmpeg and the sample you
 uploaded (CSI.ts), and I don't see any problems with the resulting file
 and WMP.
 Was the problem fixed?
 $ ffmpeg -i CSI-ts -ss 3 -crf 2 out.mp4

Comment (by ramitbhalla):

 I hope this narrows it down.

 It's the -ss 3 which is causing the Audio to break:

 This does NOT work:
 ffmpeg -i CSI.ts -ss 3 -vcodec libx264 -b 191 -acodec libvo_aacenc -ab
 192k csi.mp4

 This DOES:
 ffmpeg -i CSI.ts -vcodec libx264 -b 191 -acodec libvo_aacenc -ab 192k
 csi.mp4

 Which of the options from your original command line have to be added to
 reproduce the problem?
 (I understand that adding all options from your original command line will
 allow to reproduce the problem, the question is to find the minimal set of
 options.)

 Does the following produce a working file or is it sufficient to produce
 the broken file (or is a parameter missing for the encode to succeed)?

 there are several options
 git bisect
 or
 try to remove each command line option at a time to find the absolute
 needed set to reproduce it
 or
 analyze the output file to find out what is broken if anything.

 there may be other options, but most ffmpeg developers dont have windows
 so its kinda difficult for us to test/fix this. Also if you can confirm
 that it works with mpeg4 this itself may also be usefull to circle in on
 the bug ...

 Did you already confirm that the problem happens with libx264 but not with
 mpeg4 ?
 If yes, which options from your command line can be removed and which are
 essential to reproduce the problem?

Comment (by ramitbhalla):

 Thanks, but like I had mentioned earlier the users are insisting on using
 lix264.
 I want to upgrade ffmpeg to the latest version to fix the WTV and MPEG2/TS
 issues that were fixed recently but with libx264 broken it will not be
 possible.
 MCEBuddy has been running for years on libx264 with a strong userbase.

 Is there anyway to isolate the issue?

Comment (by ramitbhalla):

 I'm using Windows Media Player and KMPlayer. KMPlayer is not able to play
 the file while WMP does not have any audio for quite a while after which
 it suddenly appears but out of sync.

 Unfortunatley yes all the parameters are required. If I remove all the
 params (say use only -sameq it works but the quality is terrible). The
 previous version of ffmpeg works perfectly with these params. I tend to
 update ffmpeg every few months, upto  N-37915-g6cb2085 there was no issue,
 somewhere after that it broke (unfortunately I do not know how to use
 bisect etc to figure it out).

 Also mpeg4 codec quality for the same bitrate creates more artifacts so my
 users insist on using lix264.

 I tried the command with the CSI.ts, i see no desync with ffplay CSI.mp4.
 With what player do you see a problem ?
 Also a minimal command line would simplify debuging this, are all options
 needed to reproduce this issue?

 Is this only reproducible with libx264 or also with -vcodec mpeg4 -strict
 experimental -acodec aac ?

 If this is a regression, please find the version introducing the problem
 with git bisect.
